Abstract: A beam pattern of a base station antenna is refined when communicating with multiple aircraft, so that interference to adjacent beams from the base station are reduced. The method include receiving position locations from each of multiple aircraft. The method also include the receipt of an attitude of each of the aircraft as well as receipt of measurements of the pilot signals from each of the aircraft. The pilot signals were transmitted by the base station. The method also include the adjustment of an amplitude and a phase of a signal driving at least one antenna transmit element to refine the beam pattern. The adjustment is based at least in part on the pilot measurements, the position locations, and the attitude of each of the aircraft.

Abstract: A user equipment (UE) adjusts a rate of performing searches and/or measurements of neighbor cells to conserve resources of the UE. In one instance, the UE independently determines whether to perform the searches and/or measurements of the neighbor cells of first and second RATs based on a signal quality of a serving cell of a first RAT and/or a signal quality of the neighbor cell(s) of the first RAT. The UE avoids performing the searches and/or measurements of the neighbor cell(s) when the signal quality of the serving cell is above a first threshold. The UE selectively performs the searches and/or measurements when the signal quality of the serving cell is above a second threshold and below the first threshold, and the signal quality of the neighbor cell(s) of the first RAT is above the second threshold or a third threshold.

Abstract: A user equipment (UE) avoids entering a limited service state when the UE enters a weak coverage area where a communication service outage occurs with respect to a first radio access technology (RAT) and a second RAT. In one instance, the UE remains on the first RAT during the communication service outage, based on a location of the UE by preventing switching from the first RAT to a second RAT.

Abstract: A user equipment (UE) avoids entering a limited service state when the UE attempts to switch from a first radio access technology (RAT) to a second RAT when the UE experiences a communication service outage with respect to the second RAT. In one instance, the UE attempts to access the second radio access technology (RAT) from a first RAT. The first RAT may be in a service outage or have weak coverage. The UE does not reach a maximum number of network access failures in the second RAT. Rather, the UE attempts to acquire a third RAT before reaching the maximum number of retries. The third RAT may be the same as the first RAT or may be a different RAT altogether.

Abstract: A user equipment (UE) improves wireless communication when the UE returns or attempts to return to a first radio access technology (RAT) from a second RAT after a circuit switched fall back (CSFB) call failure due to a radio resource control (RRC) connection failure. In one instance, the UE successfully redirects to the second RAT from a first RAT. The UE then determines that the circuit switched fall back call on the second RAT failed. In response to the determination of the failure, the UE waits for a predetermined amount of time for second RAT re-paging or a user re-initiating the circuit switched call. The UE then performs fast return to the first RAT after the predetermined amount of time expires or in response to a user input.
